Devtron Enterprise Kubernetes Dashboard (Air‐gapped)

This documentation is for installing Devtron in air-gapped clusters. If your cluster is NOT air-gapped, consider Installing Devtron referring this documentation as air-gapped installations have certain limitations.

Pre-requisites

1. Make sure that you have podman installed on the VM from where you're executing this script.
2. Download clone-images.sh and devtron-images-ea-ent.txt.source on the VM which has public internet access as well as access to your private registry. You can use the following commands:

wget https://raw.githubusercontent.com/devtron-labs/utilities/main/scripts/devtron-installation-utlities/kubernetes-dashboard/clone-images.sh
wget https://raw.githubusercontent.com/devtron-labs/utilities/main/scripts/devtron-installation-utlities/kubernetes-dashboard/devtron-images-ea-ent.txt.source

You can also push all the images mentioned in devtron-images-ea-ent.txt.source manually to your private registry if you wish to and skip to step 6.

3. Set the values of SOURCE_REGISTRY_USERNAME and SOURCE_REGISTRY_TOKEN in clone-images.sh file (The values of these variables are separately shared with you over the email by Devtron team).
4. Set the value of TARGET_REGISTRY, TARGET_REGISTRY_USERNAME, TARGET_REGISTRY_TOKEN as well in clone-images.sh file.
5. Make the script executable and run it:

chmod +x clone-images.sh
bash clone-images.sh

Wait for all the images to be pushed to your target registry.

6. Download and unzip the devtron air-gapped helm chart on the bastion from which you are able to access your airgapped cluster.

tar -xzvf devtron-operator-0.22.73.tgz
cd devtron-operator

Devtron Installation

sed -i 's/devtroninc.azurecr.io/<TARGET_REGISTRY_URL>/g'  values.yaml
helm install devtron . -n devtroncd --set global.containerRegistry="TARGET_REGISTRY_URL" --set global.imagePullSecrets[0].name=devtron-image-pull-enterprise
